I just want to say that there are probably only a handful of games RTS (you can count them on one-hand I'm sure) that have Japan as a PLAYABLE faction built into the game, not modded, etc. Really, off the top of my head, I can only think of Red Alert 3 and that's more sci-fi than anything.
Anyways Relic, if you made a Pacific Fronts Expansion with a playable Japanese faction? I think that would absolutely be groundbreaking for the RTS genre. I know there's some other threads for Japan as a playable faction but I wanted to make my very own to show my own individual appreciation for you guys in hope that you do read this. It would be a shame not to honor those brave Americans and Japanese who fought for their lives and country in your badass game, Relic. I hope you have more factions planned
